React native expection java.lang.UnsatisfiedLinkEr

I am trying to integrate React Native with my existing Android App. I am getting the following exception, when initilizing React Native Screen:

java.lang.UnsatisfiedLinkError: dlopen failed: "/data/data/com.snapdeal.main/lib-main/libgnustl_shared.so" is 32-bit instead of 64-bit

The App is only crashing on 64-bit devices.

As per my learning so far, I've found this issue reported on React Native Repo, but the solution suggested in this thread is not helpful as I am not using any external SO library in existing App.

Apart from above, I've realized another difference in library structure on the device where my App is installed. I am comparing structure of my App vs react native demo app.

React demo App

root@generic_x86_64:**/data/data/com.react.demo/lib** # ls
libfb.so
libfolly_json.so
libglog.so
libglog_init.so
libgnustl_shared.so
libicu_common.so
libimagepipeline.so
libjsc.so
libreactnativejni.so
libreactnativejnifb.so

root@generic_x86_64:/data/data/**com.react.demo**/lib-main # ls
dso_deps
dso_lock
dso_manifest
dso_state

My App

root@generic_x86_64:/data/data/**com.my.app**/lib-main # ls
dso_deps
dso_lock
dso_manifest
dso_state
libfb.so
libfolly_json.so
libglog.so
libglog_init.so
libgnustl_shared.so
libicu_common.so
libimagepipeline.so
libjsc.so
libreactnativejni.so
libreactnativejnifb.so

Any clue is appreciated.

PS: I know react-native does support 64-bit binaries and I am not using any external library.

Add the following into app/gradle file

defaultConfig {
....

    ndk {
        abiFilters "armeabi-v7a", "x86", 'armeabi', 'arm64-v8a'
    }

    packagingOptions {
        exclude "lib/arm64-v8a/libgnustl_shared.so"
    }
}

also make sure you working with the same port.

adb reverse tcp:8081 tcp:8081

It can also help you: build.gradle (app)

android{
   ...
   defaultConfig {
      ....
      ndk {
        abiFilters "armeabi-v7a", "x86", 'armeabi', 'arm64-v8a'
      }
      packagingOptions {
               exclude "lib/arm64-v8a/libgnustl_shared.so"
               exclude '/lib/mips64/**'
               exclude '/lib/arm64-v8a/**'
               exclude '/lib/x86_64/**'
      }
      ...
   }
}

React Native doesn't provide 64-bit version of the native code and the system always fall back to 32-bit. They have resolved this issue and is scheduled to be part of the RN 0.59 release Ref: https://github.com/facebook/react-native/issues/2814#issuecomment-457644191

回答4:

Using RN 0.60.5 version.
If you guys are wondering why your app crashes if you download it from playstore, make the below changes

**packagingOptions {
exclude '/lib/mips64/'
exclude '/lib/arm64-v8a/'
exclude '/lib/x86_64/**'
//In pickFirst, replace the library name with the library that is causing error.
pickFirst '/lib/x86/libgnustl_shared.so' 
pickFirst '/lib/armeabi-v7a/libgnustl_shared.so'
}**

REASON - We are excluding all 64 bit libraries so that OS will not have confusion of which library to pick.

If you do not know which library is causing the crash, upload your bundle in Firebase test lab and then check. It will tell you which library is throwing the error
